Who knows?  There were a lot of people that got large amounts of testnet Lisk from Oliver and Joel at the start.  You can't just look at somebody with a high number of Lisk and automatically say they spammed the faucet.  Testnet Lisk is free and has no value.  It is used for TESTS.  Nobody was really keeping track of it at the start and it's only important NOW because the testnet population is having to vote for delegates since about three days ago.

This is an interesting intellectual exercise but not a practical one.
